Foreword
This Standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This Standard replaces GB/T 9764-2009, Tyre valve - Core chambers. Compared with
GB/T 9764-2009, the major technical changes are as follows:
-- Modify the core chamber number and some dimensions and requirements (see
Figure 1, Figure 2 and Figure 3; Figure 1, Figure 2 and Figure 3 of the 2009
edition);
-- Add No. 4, No. 1C, No. 2C, No. 3C and No. 4C core chambers (see Figure 4 ~
Figure 8);
-- Modify Appendix A and Appendix B (see Appendix A and Appendix B; Appendix
A and Appendix B of the 2009 edition).
This Standard uses the redrafting method to revise and adopt ISO 20562:2014 Tyre
valves - ISO core chambers No.1, No.2, No.3 and No.4.
Compared with ISO 20562:2014, this Standard has some structural adjustments.
Appendix A lists the comparison of chapter numbers between this Standard and ISO
20562:2014.
